Design Of Light Environment Of Living Space In Arctic Rigion Under Extreme Light Climate

In recent years,the economic and strategic importance of the Arctic region has rapidly increased.As an important stakeholder in Arctic issues,my country needs to continuously deepen research in various fields of the Arctic in order to better participate in Arctic affairs.Due to the high latitude,the Arctic region has extreme light and climate phenomena such as extreme day and night,which will cause obvious negative effects on peoples physiology and psychology,especially the special photoperiod can seriously interfere with peoples circadian rhythm.There are many ways to solve this problem,among which architectural design is an important aspect,and the living room is closely related to peoples daily life and sleep,and should be a key region of architectural light environment design.This thesis will discuss the problems of the room light environment in the Arctic region,and provide corresponding solutions at the architectural design level.The particularity of the light climate in the Arctic is mainly due to the exposure time,azimuth and radiant intensity of the polar sunlight and the cloudy sky.This extreme light climate will cause various problems of the human body in both visual and non-visual aspects,which need to be solved through the design of the light environment.The paper investigates the people with work and life experience in the Arctic region,understands the basic lighting conditions of the Arctic room in the polar day,analyzes the actual problems faced by the room light environment in the Arctic region,and draws the elements and evaluation of the room light environment design in the Arctic region.Standards are used as the basis for the proposed design strategy.The dissertation selects the dormitory of China Arctic Yellow River Station as a typical model for simulation experiments to study the natural light environment and optimization methods of the rooms in the Arctic.The artificial sky dome is used to conduct physical simulation experiments to simulate the actual conditions of the natural light environment of the rooms in the Arctic region.At the same time,computer software is used to analyze the light environment of typical rooms in the Arctic.Correlation analysis between simulation experiment data and simulation data to increase the accuracy of simulation.On the basis of the typical model,analyze the variables from the three aspects of orientation,space,and window opening,and summarize the relationship between each element and the natural light environment and optimization methods.According to basic research and simulation research,the goals,principles and methods of the design of the room light environment in the Arctic region are proposed.Combined with the simulation research of natural light environment,the integrated analysis of various light environment influence factors is carried out,and the optimization design strategy of natural light environment for the main body of the building is proposed.For light environment problems that are difficult to solve by the building itself,corresponding manual control strategies are proposed,including the use of occlusion,refraction,and guidance to improve and utilize natural light,and rationally set and use artificial light sources.Based on the Arctic region,this thesis systematically puts forward the design strategy of the room light environment in the Arctic region by taking the dormitory of China Arctic Yellow River Station as a typical model in accordance with the extreme light and climate conditions and the physical and psychological needs of people.This research has practical guiding significance for the improvement of the human settlement environment of existing scientific research stations in my country and the construction of future scientific research stations,and it has reference value for the light environment design of general residential spaces in the Arctic.
